Brown was suspended last season after he tested positive for clenbuterol, which is on the league’s banned substance list. He appealed the suspension and won, arguing that the result was based on eating too much meat during a trip to Mexico.

Brown’s appeal included receipts for 10 hamburgers and two steaks during his trip to Baja, according to the report.

The NFL and NFLPA sent a joint statement to players warning them about the contaminated meat that could trigger a positive test.

“There is some evidence that some meat produced in China and Mexico may be contaminated with clenbuterol, an anabolic agent which is banned by the NFL Policy on Performance-Enhancing Substances,” the statement says.

“Consuming large quantities of meat while visiting those particular countries may result in a positive test for clenbuterol in violation of the Policy. Players are warned to be aware of this issue when traveling to Mexico and China. Please take caution if you decide to consume meat, and understand that you do so at your own risk.”

Brown is recovering from quad surgery and his hoping to be ready for the start of the season.
